• Accessory Rails for Flip Up Front Sight

The sight comes with a standard mil-spec 1 1/4-inch, ambidextrous sling swivel that bolts to the body of the sight. There is a provision for the easy attachment of an optional MIL-STD-1913, ambidextrous 1 1/4-inch long dovetail for mounting flashlights, LAMs and other small accessories onto the gas block base. The installation process requires removal and replacement of the taper pins that hold the A frame sight in place. Therefore your barrel or barreled upper receiver must be sent to us for installation of this product.
